Re: Looking at a 2003 Sierra K2500 w/6.0
i agree with the above post. i changed both 02 sensors on mine just because at around 130k, the car ran the same and i did notice a change at all. i am not sure if bad o2 sensors are that big a deal, you could always buy 2 keep the receipt put em in and if that dont change it bring em back. i think they are around sixty to nintey bucks
